There are many realms in what we call "the afterlife," but right now at this very moment
your deeper, or higher, being, what some call "the soul," already exists in the afterlife realm.
You are experiencing this physical world from the spiritual realm, through a physical human body.
You are not your physical body nor are you your thoughts and feelings, you are something much
grander than those things. Human death is but a transition back to what we have always truly been.
We all know that human life is temporary but there is something within us that is permanent;
that something looks through our eyes, tastes food and drink, and uses all of the other senses a
human body may offer. We call that something "me," or "I."
Form a deep relationship with yourself and get to know that something now, while you are here on Earth.
Get to know your own soul, deeper being, or whatever you may want to call it. It is beyond words and
thoughts, but we can get to know it. It is at the core of our being; that which inhabits the body which we
call "me" or "I." "Know ThySelf" on every level is the best way to learn about the afterlife.
But this is just my opinion.
